Sea to Summit's AlphaLight Cutlery uses a durable hard-anodized aircraft grade aluminum combined with a sleek-yet-strong shape to create an extremely lightweight utensil at a surprisingly affordable price. By hard anodizing the aluminum it forms a kind of ‘exoskeleton’, so the utensils can be slimmer and lighter. This hardened shell also encapsulates the aluminum, to eliminate the risk of the alloy leaching into food.
